This doesn't make sense to me, so I'm not sure you're saying what I think
you are.
If I originate the call, my local telephone provider doesn't necessarily
know that I'm calling the NBS Time Service, and it would route my call via
the most viable way. That's not likely to be via "land-line" from Nevada
to Colorado.
In addition, the "speed of light delay" via satellite shouldn't be much
different than the speed of light delay over a copper wire...
